Patent number: 9808757Abstract: An exemplary embodiment of the present invention provides a carbon-dioxide (“CO2”) sequestration system comprising a CO2 source, a process-water source, a membrane module, and a sequestration duct. The membrane module comprises a first section, a second section, and a membrane. The first section can be configured to receive gaseous CO2 at a first pressure from the CO2 source. The second section can be configured to receive process-water at a second pressure from the process-water source, wherein the first pressure is greater than the second pressure. The membrane can be positioned between the first section and the second section and can comprise a plurality of apertures configured such that the gaseous CO2 passes through the plurality of apertures and dissolves into the process-water to form a process-water-CO2-solution. The sequestration duct can be in fluid communication with the second section and configured to transport the process-water-CO2 solution to a sequestration site.Type: GrantFiled: June 4, 2013Date of Patent: November 7, 2017Assignee: THE SOUTHERN COMPANYInventor: Dhansukhbhai V.

Patent number: 8631788Abstract: The invention provides a system whereby oxygen can be derived from seawater or from thin air at higher altitudes while simultaneously eliminating carbon dioxide from the blood. This allows prolonged underwater liquid breathing at greater depths without suffering from the bends or, alternatively, the ability of workers to breathe underwater or at high altitudes without having to rely upon air tanks or the like. The artificial gill comprises a plurality of concatenated modules each containing a semi-permeable membrane operative to transfer oxygen in a first direction and carbon dioxide in a second direction across the membrane. By providing multiple concatenated interconnected modules, oxygen becomes concentrated to allow breathing thereof. Because the system is connected in series with a person's blood supply, CO2 produced in the body is extracted and disposed of via the artificial gill.Type: GrantFiled: June 2, 2008Date of Patent: January 21, 2014Inventor: Arnold J.

Patent number: 8561605Abstract: The present invention provides an intubation device including a nasal endotracheal tube having a proximal, relative to a person inserting the nasal endotracheal tube, end and a distal end; and an introducer including an elongated member having a proximal open end and a distal blunt end, the introducer proximal open end including a hollow mouth having sidewalls for receiving and holding the distal end of the endotracheal tube. The dilator/introducer is simply a tube, solid or hollow having a hollow proximal end that will hold a distal end of a nasal endotracheal tube in place. It will act as a dilator, and once the distal end of the endotracheal tube is past the nasopharynx and is visualized in the oropharynx, the “dilator” is removed and typically discarded. A method of use of the intubation device is also disclosed.Type: GrantFiled: April 10, 2008Date of Patent: October 22, 2013Inventor: John J. Davis

Patent number: 8166968Abstract: A conjoined tube within a tube located inside a lower section of a snorkel designed to steer water droplets away from the snorkel diver's breathing path. The lower section of the snorkel has two valves. One is the scupper valve positioned at the lowest point of the inside tube. The scupper valve is a light duty valve or a low resistance one-way watertight passage intended to allow droplets of water to drain into the main reservoir. The outer tube lower section contains a reservoir for holding residual water that travels down to the bottom of the snorkel and is contained therein. During the normal clearing operation, the reservoir can be emptied and water will exit out of the lower section and into the surrounding water.Type: GrantFiled: November 6, 2006Date of Patent: May 1, 2012Assignee: Atomic Aquatics, LLCInventor: Dean R.
